Tumblr Nazerine notes that the Japanese text differs. It reads, "Only half a year ago, I was a Karate King. The power of medical science is amazing, isn't it?" The English localization does not reference "the power of medical science" (いがくのちから), which appears in the original.

So? Granted, the character's gender doesn't really matter, but the way the game's developers appear to have inserted it into the game is interesting.

The Japanese version, website Legends of Localization explains, uses "Karate King" (literally, "karate ou" or カラテおう); however, the Japanese word for king ("ou" or おう/王) isn't exclusively reserved for males, but can also be translated as "ruler" or "monarch."

But in English, the "Karate King" (カラテおう) trainer class is called "Black Belt" in English and consists only of male characters. Their female counterparts are called "Battle Girl" in English and "batoru gaaru" (バトルガール) in Japanese.

The text in both versions of X/Y makes clear allusion to Karate King.

As Twitter user @SenseiHanzo points out, the character's remark also appears to parody another non-playable Pokémon character in the game who says, "The power of science is amazing!" Below, you can see the Japanese language version of that quote.
